IMPROVEMENT IN SPRING-SUPPORTEIRS FOR CARRIAGES.

The Schedule referred to in these'Lettel-s Patent and maldng part of the same.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to. describe its construction and operation, referring to the annexeddrawin g which forms a part of this specification, and in which- Figure lis a side elevation of a carriage-spring with my supporter attached;

Figure 2 is an enlarged side view of the spring-supporter; and

Figure 3 is an enlarged side view of the inner tube of-the supporter. p

A represents an ordinary: elliptic carriage-spring, in the center of which my supporter is attached.

The supporter is composed of two coil-springs, B G, two rings, D E, and three tubes, G H I.

In the center of the lower half of the spring A, by the same bolts which secure the spring in place, is secured a plate, K, from which rises the outside tube G.

In the upper end of this tube is inserted the middle tilbe H, which is attached to and descends from "a a similar plate, K, secured in the same manner in the center of the upper half of the spring A.

Through the tubes G and H passes the inside tube 'tain distance. I

I, which, at its upper end, is provided with a pin, a, projecting through vertical slots in the middle tube H.

The lower end of the tube I is, by a pin, 12, connected with the ring E, surroundiugthe lower end of the outside tube G, said pin passing through vertical slots in this outside tube. 1

Surrounding the outside tube G and resting upon the lower ring E is the coil-spring, on top of which is placed the middle ring D.

This ring has a pin, 0, through it, which pin passes through vertical slots in the outside tube G, and prevents said ring from going upward more than a cer- A Both the tubes H and I are also slotted for this pin 6 to pass through and allow the supporter to be compressed.

On top of the middle ring D is placed the coil-spring B, surrounding the upper end of the outside tube Ur and the middle tube H, and its upper end bearing against the plate K. I

By this device the carriage-spring issupported, both when it goes down and when it comes up.
